Light-emitting diode 2835 lamp beads: Before talking about the classification of LED backlight sources, let us first understand what does LED backlight mean? LED backlight refers to the use of LED lamp beads (light emitting diodes) as the backlight source of the liquid crystal display. Compared with the traditional CCFL (cold cathode tube) backlight, LED lamp beads have the characteristics of low power consumption, low heat generation, high brightness and long life. Light-emitting diodes are expected to completely replace traditional backlight systems in recent years.
At present, the classification of this type of SMD 2835LED backlight can be divided into three-color RGB-LED lamp beads and single-color white LED lamp beads. Monochromatic white LED lamp beads use the ability of dynamic partition backlight technology and the excellent light source of tri-color RGB LED to make a qualitative leap in color and contrast compared with traditional backlights, so they are usually used in high-end TV products. It is also widely used in notebooks and liquid crystal displays. The light-emitting diode 2835 single-color white LED backlight usually uses light intake from the edge of the display screen, which is different from the light-emitting diode 2835 three-color RGB LED and the direct back light of the traditional backlight. According to the incident position of the light-emitting diode 2835LED backlight source: 2835LED backlight modules are divided into two categories according to the incident position of the light source: direct type and side type, which can be roughly divided into direct type RGB-LED, direct type white LED, and edge type white LED Wait.
